I have lost about 7lbs since my pre-op appointment but am worried liver won't be okay. What do you think?

Im on a pre op full liquid diet and have been drinking carnation instant breakfast v8 juice broth and creamed soups blended. I cheated a few times when i was absolutely hungry i made a hand full of sauteed shrimp and on other days a few bites of steak home cooked and 5 bbq ribs also home grilled.
